I would like to delete all cookie when I close the opera browser. Except a few so I don't have to login to certain sites. It looks like this is not possible in opera. Or so the Aria ai tells me.
This is rather disappointing, because in firefox this is possible.
To be honest I find the handling of cookies in chrome based browsers rather confusing. Can someone recommend a good cookie delete add-on?
